FRONTLINE correspondent John Hockenberry of PRI's The Takeaway goes inside the organizations that fought the scientific establishment, environmental groups, and lawmakers to shift the direction of debate on climate issues and redefined the politics of global warming.

This program is invaluable for any American who wishes to be informed on issues related to climate change. There is no spin, they give equal -- if not more -- time to climate deniers than to scientists and policymakers who are trying to do the right thing against deep pockets and long odds. Every elected official should be required to watch this.

Clearly and methodically discredits those leading the charge to convince America that global warming is a hoax. This film exposes their total lack of scientific expertise. It explains who is leading the campaign if disinformation and who funds their efforts. A must have for those who want the truth. I plan to use it in my college science classes.
